COMMERCIAL <br />HEAT PUMP WATER HEATERS <br />Installation Key Considerations <br />Service clearances A service clearance of 24 inches should be maintained from serviceable pans such as the T&P valve, control system components, drain valve, and anode. <br />Ambient air temperature In Efficiency Mode, the heater will minimize element use when the ambient air temperature is between 45°F and 110°F <br />Room size requirement <br />Condensate draining This water heater produces condensate and must be properly drained. <br />Ducting There is not an optional ducting kit. Discharge air from the front of the water heater must be into a suitable room. <br />Indoor/Outdoor This water heater is approved for indoor use only. <br />This is a partial list. Please reference the Installation Manual for detailed installation considerations. <br />SUGGESTED SPECIFICATION <br />For technical information, call 800-527-1953. A. 0.

Smith Corporation | 500 Tennessee Waltz Parkway | Ashland City, TN 37015 <br />Amperage/Overcurrent <br />protection <br />This water heater requires a 208 or 240 VAC single phase power supply. 208V requires 80 amp power supply at 60 Hz; 240V requires 90 amp power <br /> supply at 60 Hz. <br />Page 4 of 4 <br />AOSZE55000 <br />^Smith. <br />Recommended to have a minimum installation space of approximately 3,200 cubic feet. Installation spaces less than the recommended could result in <br />reduced water heater efficiency and performance. If the water heater is installed in a confined space with less than 3,200 cubic feet, provisions should <br />be made to ensure sufficient airflow, such as installing louvered grills or fully louvered doors to ensure the most efficient operation of the water heater. <br />Failure to do so could result in reduced heater efficiency and performance.
